Locking tube clip

ABSTRACT

A component useable with one or more tube comprises a body engageable with one or more external surface recesses of the one or more tubes. The component has a pair of jaws extending from the body for gripping an item. The component is configured, such that, in use, in a first orientation of the body relative to the respective tube(s) recesses, the component is movable along a length of the tube(s); and, in a second orientation of the body relative to the respective tube(s) recesses, the component is resistive to movement along a length of the tube(s).

FIELD OF THE INVENTION

The present invention relates to components for medical circuits. In one particular aspect, the invention relates to a component locatable about the exterior surface of a corrugated breathing tube, such as for use in the inspiratory and/or expiratory limb of a breathing circuit, or for corrugated tubes associated with surgical insufflation systems.

BACKGROUND TO THE INVENTION

In medical applications, such as with assisted breathing, the gases inhaled by a patient or user are preferably delivered in a condition having humidity near saturation level and at close to body temperature (usually at a temperature between 33° C. and 37° C.). In facilitating delivery of gases to a patient in such preferred conditions, breathing tubes (or medical tubes) may be used. Such tubes may take various shapes and configurations. One generally used configuration is (at least) an externally corrugated tube.

In various instances, the corrugated tubing is advantageously placed or positioned in certain locations relative to the patient or user. For example, the tubing may need to be held in a position or supported such that the weight of the tubing such not exert forces on the patient or user or other associated medical devices they may be using, such as masks or other interfaces. Enabling the positioning, support and adjustment of tubing between various further positioned or supported positions for patients or users would be beneficial.

In this specification, where reference has been made to patent specifications, other external documents, or other sources of information, this is generally for the purpose of providing a context for discussing the features of the invention. Unless specifically stated otherwise, reference to such external documents is not to be construed as an admission that such documents, or such sources of information, in any jurisdiction, are prior art, or form part of the common general knowledge in the art.

Further aspects and advantages of the present invention will become apparent from the ensuing description which is given by way of example only.

DETAILED DESCRIPTION OF THE INVENTION

In this specification, the terms “medical circuit” and “breathing circuit” are used to indicate the general field of the invention. It is to be understood that a “circuit” is intended to include open circuits, which do not form a complete closed circuit. For example, CPAP systems typically consist of a single inspiratory breathing tube between the blower and the patient interface. The term “breathing circuit” is intended to include such “open circuits”. Similarly, the term “medical circuit” is intended to include both breathing circuits and insufflation circuits, which are also typically “open.” Similarly, the term “medical tubing” is intended to be read as flexible tubing suitable for use in the type of medical circuits described above connecting between components of a medical circuit and providing a low resistance gases pathway between components of a medical circuit.

In the field of medical circuits, and in particular breathing circuits, including anaesthetic circuits, condensation or rain-out can be a particular problem where high humidity breathing gases come into contact with the walls of a component at a relatively lower temperature. With reference to FIG. 14, a humidified ventilation system is shown in which a patient 100 is receiving humidified and pressurised gases through a patient interface 102 connected to a humidified gases transportation pathway or inspiratory breathing tube 103. It will be appreciated the patient interface 102 may take the form of a nasal mask, oral mask, oronasal mask, nasal prongs, endotracheal tube or full-face mask, for example but without limitation.

It should be understood that delivery systems could also be continuous, variable or bi-level positive airway pressure or numerous other forms of respiratory therapy. The inspiratory tube 103 is connected to the outlet 104 of a humidification chamber 105 which contains a volume of water 106. The inspiratory tube 103 may include a heater or heater wires (not shown) which heat the humidified gases within the tube to reduce the formation of condensation. The humidification chamber 105 is heated by a heater plate 107 of humidifier base 108. The humidifier 108 is provided with an electronic controller which may comprise a microprocessor based controller executing computer software commands stored in associated memory.

In response to the user set humidity or temperature value input via dial 110, for example, and/or other inputs, the controller determines when (or to what level) to energise heater plate 107 to heat the water 106 within the humidification chamber 105. As the volume of water is heated, water vapour begins to fill the chamber above the water's surface and is passed out of the humidification chamber outlet 104. A flow of gases (for example, air) is provided from a gases supply or ventilator 115, which enters the chamber 105 through inlet 116. Exhaled gases from the patient's mouth are returned to the ventilator via a return expiratory breathing tube 130 that may also include a heater or heater wires (not shown), which heat the humidified gases within the expiratory breathing tube to reduce the formation of condensation.

It is preferable that medical tubing (for example the inspiratory and/or expiratory breathing tubes 103,130) is: resistant to crushing, resistant to restrictions in flow when bent (e.g., increased resistance to flow <50% when bent around a 1 inch cylinder), resistant to kinking, resistant to changes in length/volume under fluctuating internal pressure (e.g., resistance to compliance), resistant to leaking (e.g., <25 ml/min@6 kPa), have low flow resistance (e.g., increase in pressure@max. rated flow <0.2 kPa), electrically safe (e.g., resistant to sparks in the tubing) given an operating environment that may be oxygen-rich.

International standard ISO 5367:2000(E) (Fourth edition, 2000-06-01) is one example of how some of these desirable parameters are measured and quantified, and the document is hereby incorporated into this specification in its entirety by reference. It is preferable that components described herein meet or exceed some or all of these standards. Further, reference to medical tubes includes breathing tubes as defined in the above ISO standard.

In accordance with certain features, aspects and advantages of this invention, a component 1 is provided as an accessory for use with medical tubing. The components has particular application for the positioning and support of such medical tubing relative to a user or equipment associated with the user (e.g., user interfaces or patient interfaces, such as masks, nasal cannula and the like, briefly described above).

The ability to locate a medical tube relative to a user has certain advantages. Being able to help support the weight of the medical tubing connected to equipment associated with the user has a number of advantages including but not limited to, for example, reducing the weight transferred to a user or equipment associated with the user, which may in turn impact on the efficiency of a treatment being provided to a user, or the overall comfort experienced by a user when using such equipment.

Further, as a user moves or re-positions their body relative to the medical tubing or associated equipment, strain may be transferred to the tubing or to the user via the associated equipment. A relatively quick and effective re-positioning or re-locating of the tubing to provide support again would be useful. Certain features, aspects and advantages of the present invention attempt to provide or go at least some way towards providing at least an alternative component facilitating such advantages.

Such a component can be utilised to position or locate inspiratory or expiratory medical tubing, or other tubing associated with such medical circuits as described above. Particular application may have uses in the OSA fields, as well as in hospital situations.

According to the one aspect of the present invention, a component 1 is provided for use with a tube. The component 1 comprises a body 2 engageable with one or more external surface recesses 3 (or surface relief portions or sections) of a tube (e.g., such as those of a corrugated tube or tube with a helically recessed surface region). The component 1 includes a pair of jaws 4 that extend from the body 2. The jaws 4 can be used for attaching to or for gripping of an item (not shown). In use, in a first orientation 5 of the body 2 relative to the tube recesses 3, the component 1 is movable along a length of the tube. While in a second orientation 6 of the body 2 relative to the tube recesses 3, the component 1 is resistive to movement along a length of the tube.

In a further aspect, the component 1 provides for use with one or more tubes (not shown). The component 1 comprises a body 2 engageable with one or more external surface recesses 3 (or surface relief portions or sections) of respective one or more tubes. The one or more tubes (not shown) are receivable by the body 2, with the body 2 being engageable with the external recesses of such tubes. The component 1 includes a pair of jaws 4 extending from the body 2 for gripping an item (not shown). In use, in a first orientation 5 of the body 2 relative to the respective tube(s) recesses (e.g. corrugations of a tube or tubes), the component 1 is movable along a length of the tube(s), and in a second orientation 6 of the body relative to the respective tube(s) recesses, the component 1 is resistive to movement along a length of the tube(s).

In respect of the above, it will be seen that FIGS. 1-2 show various embodiments of a component 1 and in relation to certain tubes of helical or axial corrugation. The general configuration and arrangement as shown for the first and second orientations of the embodiments of component 1 shown by FIGS. 15-20 will be accordingly understood with reference to those FIGS. 1-13B.

Advantageously, in the first orientation 5, the component 1 is oriented in a plane such that the body 2 is engageable with certain external recesses 3 of the tube when substantially co-axial with the tube. And, in the second orientation 6, the component 1 is oriented in a plane such that the body 2 is engageable with certain other external recesses 3 of the tube when substantially non co-axial with the tube. It will be appreciated, where for example the body 2 is configured for receiving two or more respective tubes, the component 1 is adapted to operate in the same manner.

Surface recesses 3 can include surface relief features, such as repeating recesses 3 or other surface relief features such as those of a corrugated tube, or a tube having a helical outer rib extending along the length of the tube being held or engaged therewith by body 2.

FIGS. 6A, 7A and 13A show two different embodiments of the component 1 in a first orientation 5 relative to a corrugated tube. FIGS. 6A, 6B and 13A show a component 1 in a position about a linearly corrugated tube, while FIGS. 7A, 7B and 13B show a component 1 in a position about a helically corrugated tube. It will be appreciated the component 1 will also operate in the same manner on a linearly or helically corrugated tube, or those tubes where the surface recesses 3 or relief features are ribs with interposed recesses 3, whether helical or linear relief features or ribs. The component 1 embodiments as shown by FIGS. 15-19 operate in the same manner, but are configured with a body 2 adapted to engage with a pair of tubes.

The body 2 substantially surrounds the perimeter, or circumference, of the tube(s), such that a portion or portions (such as projection 7 or 20, 22 or 30) of the body 2 are engageable with the surface recesses 3 or with surface relief portions or sections. Accordingly, the component 1 is enabled to be moved along the tube when in a first body orientation, yet the component 1 being resistive to being moved along the tube when in a second body orientation relative to the tube's recesses 3 or surface relief features.

As a part of substantially surrounding the tube, an internal surface (or surfaces or portions of the internal surface) of the body 2 is or are engageable with the one or more external surface recesses 3 (or relief features) of the tube. In this manner, the body 2 may be substantially annular about the exterior surface of the tube being engaged. FIGS. 5, 11, 12 show such a component 1 in-situ about a tube, and illustrate how portions of the body 2 are engageable with surface recesses 3 or surface relief features of the tube to which the component 1 surrounds.

Turning to the jaws 4 of the component 1, in one preferred embodiment the jaws 4 are configured to be opposing upon one another, or co-acting on each other, when in their closed position 8. Such jaws 4, or other variations of these, may be configured such that they are hingedly biased toward each other in reaching a substantially closed position 8. Further, the jaws 4 can be openable from a substantially closed position 8 to enable the jaws 4 to receive and then close upon an item for gripping of that item. The jaws 4 can be openable by deflecting the jaws 4 away from each other. Manually actuating the jaws 4 to create such a deflection or opening is additionally facilitated by providing finger grips or tabs for the user of the component 1.

FIG. 3 shows one embodiment of a component 1 where the jaws 4 are displaced and yet to be moved into a co-acting or opposing relationship with each other, FIG. 4 shows more clearly how the jaws 4 are arranged when the component 1 is provided for use, reference is also made to FIG. 2 showing the grips and inter-posing arrangement of the grips on the jaws 4.

In a similar manner, FIGS. 8, 10 and 11 illustrate another component 1 embodiment, again where the jaws 4 are yet to be moved into their opposing relationship. FIG. 12 shows the opposing and inter-posed arrangement of the jaws 4 and grips of such a further embodiment.

The jaws 4 are openable and can receive and then close to grip an item enabling a more secure option for locating of the tube that is engaged by the component 1.

It will be appreciated this one or more feature, aspect or advantage of the invention provides for the re-positioning of the component 1 onto different items or objects, as and where a user desires most useful for comfort or other reasons.

Further, the component 1 allows the tube (and any attachments connected with the tube) to be re-positioned by moving of the tube when the component 1 is moved into the first body orientation that allows the component 1 to be moved along the tube (and about or from surface recess to recess or relief feature to feature) from a first set position to a second set position. When such a second set position is reached, the user re-orientates the component 1 such that the second body orientation is achieved to then prevent movement between the tube and component 1 (or at least to substantially resist movement between these). FIGS. 6A and 7A show the first orientation of a component relative to the recess or surface relief features or trough of a tube, while FIGS. 613 and 7B show component 1 when in a second orientation 6 relative to a tube's recesses or surface relief features or trough.

In one form, the portions of the body 2 engageable with the recesses 3 (or other surface relief features) are fixed or static portions of the body 2 (i.e. are not moveable). See for example the annular rib or lip portion 30 of FIGS. 8-13B, or portions 20, 22 of FIGS. 1-7B.

Various items or objects that the component 1 may be attached to (i.e. grip) includes one or more of the following: clothing, bedding, structures associated with personal clothing (e.g. personal lanyard, belt) or bedding (e.g. bed frame, mattress), structures associated with medical equipment or where a user is located (e.g. stands, bed side table), including incubators, and cots. It will be appreciated other items or objects can be used to attaching the component 1 to via the gripping jaws 4. Accordingly, when the component 1 is in the second orientation 6 and the jaws 4 are gripping of an item, the component 1 acts to locate the tube in a set position.

In other embodiments, a carer (e.g. mother, father or nurse) may hold a child or infant in a “kangaroo” style hold, and in such an instance the carer may attach the clip to their clothing such that tubing is supported without placing weight onto the patient interface and on to the child/infant.

As mentioned above, the body 2 can include a shoulder portion 10 (or finger tab portion) associated with each jaw of the pair of jaws 4. Such a shoulder portion 10 assists in providing a surface for actuation, by a user, of the jaws 4 to an open position 9. Such shoulder portion 10 can, for example, be an enlarged region of the body 2.

In use, shoulder portion 10 of the body 2 may be deflectable towards each other, such that, deflection moves the jaws 4 from a closed or substantially closed position 8 toward or to an open position 9. In return, release of the deflection provided by a user allows the hingedly biased jaws 4 to move back to a closed or substantially closed position 8. Advantageously, the shoulder portion 10 can be sized for relative ease of actuation by the fingers of a user, i.e. being finger tabs.

In respect of the jaws 4 of the component 1, one or each jaw can include a grip or grips for gripping (e.g. frictionally) of an item or object. In one form, the grips are one or a series of ridges, projections or teeth 11. Such jaw grips are preferably interlocking or inter-lockable (or interposing) with one or more corresponding grips of an opposing or other jaw.

In another embodiment, one of more of the grips can be shaped so as to expose one (or a series) of acute angled portions that face inwardly toward the body. Such acutely shaped portions may assist in helping to grip or grab the textile of a cloth (e.g.

clothing or bedding sheets). This may for example be facilitated by the acute angled portions penetrating or semi-penetrating the weave of the cloth or fabric to which the grips are attached or becoming embedded into.

In yet a further embodiment, although it should be recognised such a feature may be provided in combination with the acutely shaped portions discussed above, one of more of the grips may be shaped so as to expose one (or a series of) obtusely angled portions facing outwardly away from the body. In such a configuration, advantageously the grips allow the ease of insertion of cloth or material into the mouth of the jaws, and therefore allowing the grips (when released from their open position) to engage with the cloth or material (or object). When provided in combination with the acutely shaped portions, sets of grips may be provided that allow the relative ease of insertion of material into the mouth of the jaws, yet the ability to easily remove the material from the grips is reduced by the improved gripping capability of the acutely shaped portions.

Such a component 1 may be formed of any suitable material allowing the above described features and deflection characteristics. It may be preferred that such a component 1 is however provided of a suitable, although not necessarily, medical grade material and, may for example, be of a suitable polymeric material.

In a further form, in the first orientation 5, the internal surface of the body 2 may comprise at least one first projection 20 engageable with a corresponding first recess of the tube or of a first respective tube, and at least one second projection 22 engageable with the same or another recess located near the first recess in which the at least one first projection 20 is engageable. And, in the second orientation 6, the internal surface of the body 2 may comprise at least one first 20 and at least one second projection(s) 22 that are engaged or engageable with a recess or recesses 3 (or other repeating surface relief features) of the tube, or respective tubes, such recesses separated from one another by a distance along the length of the or each respective tube.

When in the second orientation 6, this further form provides for the at least one first and at least one second projections 22 to act on the tube, or its recesses 3 or a part thereof (or surface relief features), to restrain (or resist) the component 1 from being moved between recesses 3 (or surface relief features) or along a length of the tube.

As illustrated by FIGS. 1-5, the component 1 comprises two first projections 20, and a single second projection 22. FIGS. 5-7B illustrate such a component 1 engageable with a tube and in the first and second orientation 6.

As shown by FIG. 6A in the first orientation 5, the two first projections 20 are engageable with a corresponding first recess of the tube, and the single second projection 22 is engageable with the same or another recess located near the first recess in which the at least one first projection 20 is engageable (i.e. in an orientation or position when the component 1 is able to be moved along the tube with relative ease).

As shown by FIGS. 6B and 7B in the second orientation 6, the two first projections 20 are engageable with a corresponding first recess of the tube, and the single second projection 30 is engageable with a recess of the tube separated from the first recesses 21 by a distance along the length of the tube (i.e. in an orientation or position when the component 1 is resistive to being moved along the tube).

In yet a further form, the component's body 2 can comprise of at least one lip for engaging with at least one recess of the tube, for example as illustrated by FIGS. 8-13B. In such a form, the lip can be one or a series of projections extending in a substantially annular from and about a surface of the body 2. Such a lip or lips are those portions of the body 2 that are engageable with the one or more external surface recesses 3 of the tube, as shown by FIGS. 11, 12. FIG. 13A illustrates such component when in a first orientation 5, where a second orientation 6 of such a component is similar to that as shown by FIG. 13B (but as shown in relation to a helically corrugated tube form). Similarly, the tube may be of axial corrugations (i.e. not helical), and the component 1 shown in FIG. 13A may be provided to operate in the manner (orientations) as shown by FIGS. 6A, 7A or when the tube has helical corrugations, as shown by FIGS. 7A, 7B.

As shown by FIGS. 15-20, the body 2 is engageable with one or more external surface recesses of respective one or more tubes (multiple tubes not shown, but body as shown is configured for receiving a pair of tubes). The body is configured, such that for each respective tube, at least one first projection 7, 20, 50 is engageable with a corresponding first recess of a respective tube. And, the body is also configured, such that for the same tube, at least one second projection 7, 22, 51 is engageable with the same first or another recess, of the same respective tube.

The component 1 shown by FIGS. 15-20, being of a multi-tube engaging body form, can be moved to be in the first orientation (e.g. the first orientation being as shown for example in relation to the single tube component embodiments of FIGS. 1-13B).

In such a first orientation, the internal surface of the body comprises, for each of the respective one or more tubes being engaged by the body, at least one first projection 7, 20, 50 engageable with a corresponding first recess of a respective tube, and at least one second projection 7, 22, 51 engageable with the same or another recess, of the same respective tube, located near the first recess in which the at least one first projection is engageable. Likewise, a further set of at least one first projections 7, 20, 60 and a further set of at least one second projection 7, 22, 61 is provided for engaging with a second tube. It will be understood that the body 2 may be adapted or shaped to receive and engage with one, two or more than two tubes.

The body 2 is engageable with a pair of tubes via the portions or projections 7, the projections operating in the manner as described previously. A pair of opposing jaws 4 are provided that may be deflected into an open position by a user, with teeth 11 (not shown in FIG. 20) that can grip an item. In the embodiment shown, each one of the pair of tubes to be engaged are fitted into the distinct regions of the body 2. The body 2 comprises portions or projections 7 which engage with the external surface recesses of the tube. It will be appreciated such a component 1 may be shaped for engaging with only one, or two or more than two tubes. Such a component also comprises of a retainer 40, as will be described in more detail below.

In addition, it will be appreciated the various embodiments described above, and as illustrated, may include a retainer portion for retaining an accessory, for example an accessory that may be associated with the tube, such as an electrical cable or sensor cable (e.g. a temperature probe cable). The retainer portion may even be configured for receiving a lanyard such as those that may be looped about a user's neck for further supporting the weight held by the clip and grips when gripping an item. However, preferred forms for the retainer 40 include those where a cable may be friction fitted into the retainer portion or region. Such a retainer may be shaped to receive and hold cable in in-situ, such as a temperature probe cable that may be associated with a controller or control system for a heated or electrically powered medical breathing tube.

As shown in the embodiments of FIGS. 15-20, a retainer 40 is provided about an external surface of the body 2. Those embodiments illustrated by FIGS. 1-13B may also include a retainer, although are not specifically shown. It may also be appreciated that the retainer 40 portion may be provided about an internal surface of the body 2, appropriately positioned to be non-interfering with positioning or engaging of the tubes to which the body 2 is engageable.

The foregoing description of the invention includes preferred forms thereof. Modifications may be made thereto without departing from the scope of the invention.
